Lapping
Manifestations
- Occurs when the color of the paintappears to be lighter or thicker at the point where wet and dry layers overlap during the application.
- Causes
- Not maintaining a “wet edge” by using the best brush stroke technique.
- Using low quality paint.
- Solutions
- The way to maintain a wet edge is by applying the paint towards the area that is unpaintedand back to the surface that has just been painted.
- This technique is referred to as “wet to dry” and results in the surface looking smooth and uniform. This can also be achieved by painting a smaller area at a time.
- Plan ahead to end brush strokes at a natural breaking point, a door or window for example.
- This takes on an even greater importance when applying stain to untreated wood. Generally speaking, alkyd paints provide a first rate wet edge appearance.
